PCB warpage downwards max. 0.5 mm

Use the magnetic pin supports, to achieve

this value.

When there is warpage under 2 mm, the

inkspots in the center of the board are also

within the focus of the digital camera. When

all the tolerances are taken into account,

this value is reduced to 1.5 mm.

You should also note that the warpage

reduces the component height.

General

Wide boards tend to deflect

during placement such that,

under certain circumstances,

the components can no lon-

ger be placed with the

desired accuracy. Highly

curved PCBs also affect the

placement accuracy. This

problem can be easily recti-

fied by fitting support pins on

the lifting table.

Smart Pin Support

The support pins are auto-

matically placed on the lifting

table with the help of the

Smart Pin Support option. A

gripper unit is used to pick

the support pins up from spe-

cial magazines and place

them in the prescribed posi-

tions.

Before you place a smart

support pin, the placement

area is cleaned from any

contaminants with a gentle

blast of air. In addition, the

correct position of the sup-

port pins is checked after

placement, with the PCB

camera.

Magazines

There are two different mag-

azines available for auto-

matic changeover to max. 10

support pins in the various

machine configurations.

These magazines are fixed

to a magazine holder and are

fitted to the component trol-

ley docking unit.

Programming

The positions of the support

pins in the machine can be

defined for each board side,

in the SIPLACE Pro Board

Editor.

A 3D diagram of the board

and support pins allows you

to detect and avoid potential

collisions with components,

even during stepped trans-

portation of extra long

boards.

Component trolley

SIPLACE SX

The SIPLACE SX compo-

nent trolleys are independent

and easily maneuverable

modules. The SIPLACE SX

machines can accommodate

two component trolleys, each

with 60 tracks. If a WPC5/

WPC6 is set up at one of the

locations, the other location

can accommodate a compo-

nent trolley with 30 tracks.

The tape reels are taken up

into the tape container of the

component trolley. A cutting

device on the machine auto-

matically cuts the used tape

material. The component

trolleys can be set up directly

on the machine or at an

external setup area with

feeder modules. The benefits

of offline setup are that the

configurations can be pre-

pared without stopping the

line. This allows the setup to

be changed very quickly

using the changeover table

principle. The SIPLACE SX

component trolleys also sup-

port fast setting up and tear-

ing down of feeder modules

even during the placement

process.

The component feeders are

at rest during the placement

process - allowing tapes to

be spliced without stopping

the machine. With the help of

an optional component bar-

code reader and the Setup

Center option, the barcodes

on the tape reels can be read

and checked.

This ensures the correct

assignment of components

to tracks and the traceability

of PCB placement with the

Traceability software.

For safety reasons, unoccu-

pied locations are fitted with

so-called dummy feeder

modules.
